PDP Overview 22.1
22.1.1 Overview
PDP is specially used to discover network equipment, that is, it is used to find all neighbors of a known device.
Through PDP, the network management program can use SNMP to query neighboring devices to acquire
network topology.
Our company’s switches can discover the neighboring devices but they do not accept SNMP queries.
Therefore, switches only run at the edge of network, or they cannot acquire a complete network topology.
PDP can be set on all SNAPs (e.g. Ethernet).
